Got Promoted!

Found out yesterday I was promoted and work never told me. Typically in the academy you go in as a trainee and have to wait a year to become a level one. There is no exact path to becoming a two so most likely you stay a one unless you become a SGT or above. I got a raise in July that I thought was related to my current position and didn't think anything about it. But seems they put in and were able to promote me to a two, which is great, but they never told me. Seems now I out rank three of my instructors at the academy...won't mention that when getting smoked though!
